On the basis of the previous works by the authors, a continuous approach to the calcination-hydration activated sintering of the natural MgO-CaO series materials of high purity was studied with putting much emphasis upon the effect of the ratio of MgO/CaO on the sintering behaviour and upon the resistance of grogs to disintegration as well. It is found that the densification of the two-phase materials is practically completed when the specimens fired at 1400℃ and developed the highly direct-bonded...

On the basis of the previous works by the authors, a continuous approach to the calcination-hydration activated sintering of the natural MgO-CaO series materials of high purity was studied with putting much emphasis upon the effect of the ratio of MgO/CaO on the sintering behaviour and upon the resistance of grogs to disintegration as well. It is found that the densification of the two-phase materials is practically completed when the specimens fired at 1400℃ and developed the highly direct-bonded basic grogs of fine microstructure at 1600℃, while that of one-phase end members grows a lot of exaggerated grains with moderate intragranular pore formation resulting in lowering of the density. The activated sintering of the calcination-hydration specimens seems to be related to the adsorption-desorption of OH~- by CaO and MgO. The resistance to disintegration decreases with the increase of their CaO content.

本工作在前文的基础上进一步研究整个MgO-CaO系列材料的活化烧结规律,着重探讨MgO/CaO之比对轻烧-水化试样烧结行为的影响和烧结试样的抗水化性。试验工作证明,天然高纯MgO-CaO系列的两相材料,用轻烧-水化方法,可以在1400℃烧后基本完成致密化过程,在1600℃烧后可得显微结构良好和高度直接结合的MgO-CaO熟料。二端员原料烧结时,晶粒异常长大,密度低,闭气孔率高。轻烧-水化试样的易烧结主要同CaO和MgO对OH-的吸附-脱附作用有关。
